    First test of the year, any suggestions

    Opened pool on 4/3 and water looks great. Struggled the first half of last summer with the pool store, then switched to TFP and have been very happy. Let pump run for 5hours and then tested.

    FC:9 CC:0 pH:7.3 Alk:130 CH:350 CYA: less than 30. Water Temp: 49

    I have chlorine sticks in to raise CYA, then will switch to bleach, not sure if I would be better off buying stabilizer. Would like to bring the pH up, is it worth adding soda ash, or just let it come up on its own?

    With the high TA you're showing, the pH should raise by itself. The trichlor will tend to push the pH down, though. There's nothing wrong with 7.3, so if it stays in that range, you're golden.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
